Great post on which type of bulbs are used for each light. I was wondering if the halo is the halogen bulb or the xenon. Is that different from the high beam? I just want to make sure I don't mix my stock bulbs with LED bulbs

Had to do some research to replace a brake light on my E92 (pre-LCI) and "W16W" as you all probably know is something that you can't go into the parts store and ask for... put together a list of Sylvania part numbers that you can actually buy in the US... hope this is helpful. I just did the exterior lights but will flesh this out if I need to replace any of the interior ones.

There's three brake light bulbs per side - two W16Ws in the fender, which are the normal brake lights, and one H21W in the trunk lid, which only comes on under hard braking or as a rear fog if you have enabled them. The actual tail/running lights don't use bulbs, they're LEDs.

That is very useful info, thanks ! I think this should be clarified in OP.

Is there any way w/o any ohm meters and such to test out these bulbs ? For the reg brake you can in your garage but for the hard brake ones you can't...

Just turn on your rear fog lights

That sounds like a smartass answer but I'm still pissed off that BMW saw fit to not allow us to use them over here, that was the first "mod" I ordered for my car, literally the first weekend after getting it.

Just edited post #96; apparently Osram is still making "stealth" WY5W bulbs for your repeaters even though you can no longer buy them at your local BMW dealership. The package is simply marked WY5W Diadem Chrome. Probably have to order them online, I haven't seen any in stores (but have seen equivalents from more ricer-oriented brands, but I like to stick with names like Sylvania, Osram, etc.)

Prompted by another thread this AM, I finished up the interior bulbs, this is again for a Pre-LCI car (2009) don't know if LCI are different.

I could not verify the rear footwell lights as I couldn't get the lenses out with my hands and my plastic trim spoons are in a very safe place (I know where they are, it's just a PITA to get to them) but I'm pretty sure those are right based on pics found on the interwebs.

Does anyone know how to take a spreadsheet and export it to a format that will allow me to post it here as an attachment, so if you wanted to print this nicely formatted and keep it in your glovebox or owner's manual folder you could?

By the way if you are looking up bulbs for your car and the ECE number is listed in the owner's manual, this Wikipedia page has some of the numbers you can find in the US listed for the more common bulb types

I added some of them myself as I've got bulb charts for three different German cars saved on my PC, as I've stated before this isn't the first time I've done this. Had I found that page (if it existed) years ago would have saved me some slogging through catalogs and reading of faint little numbers on bulb bases!

What would be nice is if we could come up with a master list for all different E9xs... I could see possible differences between

E90
E91
E92/E93

then there's pre- and post-LCI

Now this is something that I'm usually good at pulling together because having worked on scads of old Studebakers I've actually cross-referenced tons of Stude factory part numbers to trade numbers or aftermarket part numbers (esp. for things like fan belts, generator brushes, things like that.) But that is a rabbit hole I don't really need to go down today when I should be looking for a job instead... I've already done the best job I could with the pre-LCI E92 which I actually have at my disposal to inspect (and what I actually need the bulb chart for...)

I've been searching for a while now and find so many different values.

I'm looking to swap side markers and reverse lights on a '13 LCI E92. (want white side markers and much much brighter reverse lights for use behind tinted windows in the city)

Has anyone determined the final type of bulb? I've read H21W, which doesn't seem too specific. I've read 921 on websites like E92-Lighting. I've read P26WY (or w/e that one is, which isn't LED so I'm pretty sure that's not it). edit - i've now seen 921 and 194 as potential side markers? though some sites suggest 921 are reverse lights too?

Searching through I only found a couple of "lists" but none seem to be up to date!
